As a member of a minority, I can tell you that the world is made for people who are right handed. It is true that right handed people have a dominant left brain. Left handed people use the right side. Therefore, only left handed people are in their right mind!
Nearly all things are made for right-handed people, and lefties have to live in the world designed for righties. We struggle with many things – binders, butter knives, driver’s cup holders, keyboards, game controllers, computer mouses, scissors, golf clubs, baseball gloves, watches, and even door knobs – I could go on and on. I’ll bet that most lefties have bad penmanship, because it’s more difficult to push a writing instrument than to pull it, AND the left hand follows the pen or pencil, so it picks up ink and lead along the way, smearing the hand and the paper.
Some facts:
Only about 10% of the population is left handed.
While many people are left handed, very few are 100% left handed. For example, many Left handers golf and bat right handed. On the other hand, there is a high percentage of righties who are 100% right-handed. I am one of those who golfs and bats right handed, or at least I did when I still golfed and batted. I could putt either right handed or left handed with equal accuracy.
Lefties are also called “southpaws”. The term was coined in baseball to describe a left handed pitcher.
Sinistrophobia is the fear of left-handedness or things on the left.
During the 1600’s people, thought left handers were witches and warlocks.
Left-handed legend Ned Flanders outside the Leftorium
History is filled with famous left-handed people, including: Julius Caesar, Aristotle, Alexander the Great, Mahatma Gandhi, Joan of Arc, Napoleon Bonaparte, Queen Victoria, Queen Elizabeth II, the Queen mother Elizabeth, Prince Charles and Prince William.
Some of the most well-known inventors were left-handed like Isaac Newton and Benjamin Franklin. Leonardo da Vinci and Albert Einstein were also lefties. So is Mark Zuckerberg, as was Steve Jobs. Bill Gates too.
Presidential Left handers: James A. Garfield, Herbert Hoover, Harry S. Truman, John F. Kennedy, Ronald Reagan, George H. W. Bush, Bill Clinton and Barack Obama. That subset is much higher than the average. 44 men have become president of the United States. Eight of those were left-handed, or 18%.
Famous notorious left handers include: Osama bin Laden, Boston Strangler, and Jack the Ripper.
It is believed that all polar bears are left handed.
There is a rumor that octopuses have but one right hand. Scientists are diligently studying this issue.
Left-handed people process information more quickly.
Left-handed college graduates have a 26% greater chance of becoming rich.

In Ham Radio, an automatic keyer would produce constant dits with the thumb and constant dahs with the forefinger of the right hand. As a “rightie” that is the norm. If I turn the keyer around so it’s facing away from me, instead of at me, I could use my left thumb and forefinger to send code. I am not ambidextrous. Jimi Hendrix was a southpaw that played a right handed Stratocaster guitar, Left handed. Don’t know if he reversed the strings or not though.

Because I write with my left hand, I’m considered a lefty, but with most things I’m ambidextrous, and some things I’m right handed. My MIL was left handed, but when she was a child in school, that was considered a bad thing, so the nuns tied her left hand behind her back so she had to use her right hand to learn how to write. As an adult, she could write with both hands.
My husband and I are both left handed. Our daughters are both right handed. My late brother was completely left bodied. Couldn’t do anything that required fine motor skills with his right hand. He worked with a lot of power tools, all of which were designed for righties, and managed.
The sewing machine is one thing that’s designed for left handers, because it was invented by a left handed woman.

I’m in. I do many things lefty, but a fair amount from the wrong side. I’m not ambidextrous, and not 100% lefty. I have one sister who is 100% lefty, and the other is 100% righty. We can track the left-handed to my maternal grandfather. Neither parent could do much with their left hand. Here’s what I do lefty –
Write, eat, tennis, racketball, hammer, screwdriver. Righty – throw ball, golf, bat, bowl, shoot.

Lefty here too!
I diligently practiced to be ambidextrous when I was younger, just because.
There’s definitely strengths and weaknesses to note tho.
Lefty do betters: Write, anything requiring fine skills, like stringing beads or sticking a pin (darts game or needles) in a precise spot, managing a screwdriver efficiently, drilling, crossbow, etc.
Righty do betters: More strength related things….Hammering, throwing, lifting/carrying heavy things, handling guns.

Over many years of practice I have found ambi to be the best in so many skills. Hammering with both hands at once for many hours earlier today on parts that really can’t be made quickly any other way. Welding too.
I found one hand sort of teaches the other when acquiring new skills. Mediated by speaking aloud to self. Makes the learning go well and quickly. Kinda goofy in appearance I know, having been laughed at many times on jobsites. That hollow nervous titter wherein they are not sure why they think it’s funny. It must be hardwired.
